Which statement about transcription of ribosomal RNA is false?
A) Ribosomal RNA is transcribed by RNA polymerase I.
B) A single pre-RNA gives rise to the 18S, 5.8S, and 28S rRNAs.
C) TBP binds the TATA sequences in the promoter of the ribosomal gene.
D) Two transcription factors, UBF and SL1, bind the RNA gene promoter and recruit polymerase I to form the initiation complex.

Question

TBP (TATA-binding protein) is associated with RNA polymerase II transcription and binds to TATA box sequences in promoters of many genes transcribed by Pol II, not ribosomal RNA genes transcribed by RNA polymerase I. Ribosomal RNA genes typically do not contain TATA boxes in their promoters.
